the class DefaultRepositoryProxyConnectors method transferFile.

/**
 * Perform the transfer of the file.
 *
 * @param connector         the connector configuration to use.
 * @param remoteRepository  the remote repository get the resource from.
 * @param remotePath        the path in the remote repository to the resource to get.
 * @param repository        the managed repository that will hold the file
 * @param resource          the local file to place the downloaded resource into
 * @param requestProperties the request properties to utilize for policy handling.
 * @param executeConsumers  whether to execute the consumers after proxying
 * @return the local file that was downloaded, or null if not downloaded.
 * @throws NotFoundException    if the file was not found on the remote repository.
 * @throws NotModifiedException if the localFile was present, and the resource was present on remote repository, but
 *                              the remote resource is not newer than the local File.
 * @throws ProxyException       if transfer was unsuccessful.
